What I said earlier is that Cheney and Bush came out for McCain several days earlier than Thompson. They helped put the seal of approval on McCain as a done deal.
Thompson waited a few days longer. He COULD have endorsed McCain before Super Tuesday, but he didn’t.
So I find it hard to believe that Thompson was nothing but McCain’s Trojan Horse. If he had been purely working for McCain, he probably would have endorsed a little earlier, like the governors of Florida, Texas, and California. But coming out now is just accepting reality.
